UNITED STATE-s PATENT (murenC W. A. REX, OF NEWVILLE, INDIANA.

l-MVPROVED PUNCH.

Specication forming part of Letters Patent No. 59,453, dated November 6, 1866.

To all whom it may concern:

Be it known that I, W. A. REX, of Newville, in the county of De Kalb and State of Indiana, have invented a new and useful Improvement in Punches 5 and I do herebyr declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specication, in which- Figure l is a side view of a punch with my improvement attached. Fig. 2 is a detail sectional view of the same, taken through the line w x, Fig. l. Fig. 3 is a side view of one ofthe cutter-tubes detached from the stock.

Similar letters of reference indicate like parts.

My invention has for its object to furnish an improved means by which the cutter-tubes may be readily and quickly attached to and removed from the stock, and securely held therein while the tool is being used; and it consists of the combination of a spring-catch and removable cutter tube or tubes with each other and with the punch-stock, as hereinafter more fully described.

' A is the punch-stock, the parts or halves of which are constructed and pivoted to each other in the ordinary manner.

Through one of the jaws, a', of the stock A is formed a square hole for the reception of the shank b of the cutter-tubes B. In the side of the jaw a. is formed a groove, leading back from the square hole before described, for the reception of the spring-catch C, as shown in Figs. l and 2. The rear part of this groove is deepened for the reception of the spring c',

which holds the catch G closed by pressing against the under side of its rear end, as shown in Fig. 2.

The catch C is pivoted within the groove in which it works by a pin, c2, as shown, and

has a projection formed upon the under side the cutter-tubes B is formed a notch for the.

reception of the projection formed 4upon the catch C, as before described.

By pressing upon the rear end of the catch O its forward end is lifted away from the shank b of the cutter-tube B, allowing said cuttertube to be removed and replaced with another of the desired size.

I claim as new and desire to secure by Letters Patent- The combination of the spring-catch C and removable cutter tube or tubes B with each other and with the punch-stock A, when the said parts are constructed and arranged substantially as herein shown and described, and for the purpose set forth.

W. A. REX.
